Popis:	Satisfactory establishment of sapota is one of the major challenges in India due to poor seedling growth in the nursery. A study was undertaken on co-inoculation of sapota (Manilkara achras (Mill) Forsberg) seedlings with mycorrhiza fungus (Glomus mosseae) and mycorrhiza-associated bacteria (MAB) to establish healthy sapota seedlings under nursery conditions. Based on the survey from different sapota cropping systems in India, four bacteria were isolated from G. mosseae spores and identified as Brevibacillus parabrevis (HM590702), Pseudomonas putida (HM590707), B. choshinensis (HM590701) and Providencia rettgeri (HM590704) by polymerase chain reaction amplification of 16S rRNA. These four bacterial isolates were chosen because of their growth-promoting attributes; phytohormones, siderophore and hydrogen cyanide production; antifungal and enzyme activity; and phosphorus and zinc solubilization, and were evaluated with G. mosseae for growth promotion and mycorrhizal development in sapota seedlings. Among th...
